Propylene glycol is only slightly more poisonous than water according the the msds. The LD50 for PG is between 18,000mg/Kg to 21,000mg/Kg depending on whether it is a rat or rabbit tested. Water is usually just listed as >90mg/Kg in the msds, but you can find studies that have seen LD50's at arount 25,000mg/Kg for rats.

In other words, LD50 is Lethal Dose 50% of the time. So to be lethal, I would have to take around 20,000mg X my body weight of 84Kg or 1,680,000 mg of propylene glycol at a time to have a 50% chance of lethal side effects. Considering I inhale about 4mg a week, I think I'll be all right.

Propylene glycol is considered to be a food safe additive and is used extensively as a medical inhaler for various drugs, if it was as poisonous as you scare mongers seem to think, I think the FDA would be cracking down on the eCigarette's, but they aren't.

I do know that it is an effective delivery method, I have been taking it this way for a few months and have seen significant progress, although at my current concentration (50% concentrate and 50% 24mg/L nicotine PG) there is too much Ainterol concentrate to hit it often enough to satisfy my nicotine cravings (a typical smoker needs about 3ml of 12-14mg/L PG a day), so I am still smoking regular cigarettes. My next batch I'll cut the concentration of ainterol down so I can hit the nicotine laced pg more often.
